Door Knob & Deadbolt Replacement

If your front door still relies on a wobbly, decades-old door knob lock, you are not alone — a large share of Bronx apartments and attached homes were built when single-point locking hardware was the standard. The problem is that worn tumblers, loose spindles, and factory-grade cylinders that can be defeated by someone who simply knows how to pick a door knob lock are no longer acceptable risks on a busy block in Fordham, Tremont, or Co-op City. At 24H Bronx Locksmith, our mobile team comes directly to your address — no trip to a hardware store, no scheduling a week out — and replaces or upgrades your hardware the same day you call.

Open 24 hours, 7 days a week · Licensed, bonded & insured

We specialize in door knob and deadbolt replacement as a combined service because the two work together: a quality door knob with lock and key handles daily traffic while a properly installed deadbolt provides the bolt-throw depth that resists kick-in attempts. Our experienced, insured technicians carry a full stock of residential hardware — from heavy-duty mortise lock assemblies to modern keypad lock door knob sets — so the work is usually completed in a single visit. Whether you manage a two-family in Mott Haven or own a condo near the Yankee Stadium corridor, we confirm an exact up-front price before a single screw is turned. Call 718-878-5183 any hour — we answer 24/7.

Why Door Knob & Deadbolt Replacement Matters for Bronx Homes — 24H Bronx Locksmith

Why Door Knob & Deadbolt Replacement Matters for Bronx Homes

Door hardware fails in predictable ways: the cylinder wears down so keys bind, the latch bolt starts sticking in winter humidity, or the knob body develops enough play that the spindle slips before the latch fully retracts. Any of these conditions means your door is either harder to open legitimately or easier to force open by someone who should not be inside. In Bronx rowhouses and multi-family walkups, where hallway doors separate shared lobbies from individual units, a compromised lock door knob is a direct liability for every tenant on the floor. Replacing the hardware does not just restore convenience — it restores the door to the security level the frame was designed to support.

Adding a deadbolt at the same time is almost always the right call. A standard door knob lock engages a spring-latch that can sometimes be slipped with a credit card; a deadbolt throws a solid steel bolt a full inch or more into the strike plate and door frame. Together, they create layered resistance. Our technicians also inspect and, when necessary, upgrade the strike plate to a heavy-gauge version with three-inch screws that anchor into the stud, not just the jamb wood — a detail that makes a measurable difference in real-world kick-in resistance.

Mortise Lock Upgrades and Double Lock Door Knob Options

Many older Bronx buildings — particularly pre-war six-story walkups on the Grand Concourse and brick two-families throughout Pelham Bay — were originally fitted with mortise lock hardware. A mortise lock is a rectangular cartridge that sits inside a pocket cut into the door edge, combining a latch bolt, a deadbolt, and sometimes a privacy function in one unit. When a mortise lock cylinder cracks or the case itself strips out, a simple knob swap will not fix the problem; the entire cartridge usually needs replacement or a skilled re-keying of the existing case. Our technicians are experienced with both legacy mortise lock formats and current ANSI-grade mortise lock sets, so we can match the replacement to your door thickness and backset without cutting new pockets or patching old ones.

For doors that need more than one locking point, we also install double lock door knob assemblies — hardware that integrates a keyed lock directly into the knob body in addition to a separate deadbolt above it. This setup is popular in Bronx garden apartments where management requires two keyed points but the door stile is too narrow for a full mortise lock pocket. We source hardware from manufacturers including Schlage and Kwikset and discuss grade ratings with you before ordering, so you understand what ANSI Grade 1, 2, or 3 means for your specific door and daily use pattern.

Smart Lock Door Knob and Keypad Options — Modern Security Without Drilling New Holes

The demand for smart lock door knob and keypad lock door knob products has grown sharply in the Bronx as more residents manage rental units remotely or simply want to stop carrying physical keys. A smart lock door knob replaces the existing knob and integrates Bluetooth, Z-Wave, or Wi-Fi connectivity so you can lock and unlock from a phone, assign temporary codes to dog walkers or repair crews, and review an access log. A keypad lock door knob goes one step further by eliminating the key entirely for day-to-day entry while retaining a physical key override for emergencies.

Our technicians are experienced with installation of both product categories and will walk you through pairing the device to your home network or smart-home hub before we leave. We also advise on placement — for example, a smart lock door knob mounted on a steel fire door common in many Bronx high-rises may require a different adapter plate than the same model on a solid-wood residential door. Because we stock a range of hardware in our mobile units, we can usually install the same day you call rather than ordering and scheduling a second visit. And if you have a door knob with lock for bedroom use — say, a home office or a room housing valuables — we carry privacy and keyed options for interior doors as well.

If you are ready to discuss which hardware grade fits your home, call 718-878-5183 — our team is available 24/7 and can give you a clear, up-front quote with no surprises.

Frequently asked questions

Answers to what our customers ask most. Still unsure? Just call.

How much is a locksmith in the Bronx for door knob and deadbolt replacement?+

There is no single flat number because several factors shape the final quote: the type and grade of hardware you choose (a basic door knob with lock costs less than a smart lock door knob or a full mortise lock assembly), whether the job is straightforward or requires door frame work, the time of day the call comes in, and travel distance to your address. What we commit to is confirming an exact up-front price before any work begins — you know the full amount before we pick up a single tool. Call 718-878-5183 for a specific quote based on your actual situation.

How much is the average locksmith charge for adding a deadbolt to an existing door?+

The total depends on factors including the deadbolt grade you select, whether your door already has a properly sized bore hole, whether the strike plate needs to be upgraded, and whether the call happens during standard hours or overnight. A door that is already prepped for a deadbolt will cost less in labor than one that needs boring. Our technicians assess the door on-site and give you a firm, all-in price that covers parts and labor before starting. There are no charges added at the end of the job.

Who is the best locksmith near me in Bronx, NY for mortise lock replacement?+

The right locksmith for a mortise lock job is one whose technicians have hands-on experience with both legacy mortise lock cartridges common in pre-war Bronx buildings and current ANSI-grade mortise lock sets. You should also confirm the provider is insured and uses a mobile operation — meaning they come to your address rather than requiring you to bring hardware to a shop. At 24H Bronx Locksmith, our experienced, insured technicians have worked on mortise lock hardware throughout the Bronx, from Grand Concourse walkups to Riverdale co-ops, and we carry replacement stock in our vehicles so most jobs are completed in a single visit.

What is a locksmith call out fee, and does 24H Bronx Locksmith charge one?+

A call-out fee — sometimes called a dispatch or service fee — is a base charge some locksmith services apply just for sending a technician to your location, separate from the cost of the actual work. Fee structures vary widely by provider. At 24H Bronx Locksmith, we are transparent: we confirm all charges, including any dispatch component, as part of the up-front quote we give you before work begins. Nothing is hidden, and nothing is added after the job is done. Call 718-878-5183 to get a clear breakdown for your specific job.

Is there a 24-hour locksmith in Bronx, NY who can replace a door knob lock tonight?+

Yes — 24H Bronx Locksmith operates around the clock, every day of the year, including weekends and holidays. We are a fully mobile operation, meaning our technicians travel to your address in the Bronx whether you are in Co-op City, Hunts Point, Kingsbridge, or anywhere else in the borough. If your lock door knob fails late at night or you discover a security issue on a Sunday morning, call 718-878-5183 and we will dispatch a technician to you. We carry residential hardware in our vehicles, so same-night installation is typically possible without a return trip.

I've heard people talk about how to pick a door knob lock — does that mean my knob lock isn't secure?+

Standard spring-latch door knob locks do have known vulnerabilities, which is exactly why security professionals recommend pairing them with a deadbolt and ensuring the cylinder meets at least ANSI Grade 2 standards. Rather than focusing on picking methods, the more practical takeaway is this: if your current hardware is older, low-grade, or showing wear, it is time for a replacement. Our technicians can assess your existing lock door knob and recommend an upgrade — whether that means a higher-security cylinder, a mortise lock, or adding a deadbolt — that addresses the vulnerability without requiring you to understand lock mechanics yourself. Prevention is always more effective than reacting after a problem occurs.
